DTC Troubleshooting (cont’d)
Problem in Lock-up Control
System
NOTE:
• Record all freeze data and review General
Troubleshooting Information (see page 14-3) before
you troubleshoot.
• Keep replacement control solenoid valves on hand:
– Lock-up control solenoid valve assembly (lock-up
control solenoid valve/shift control solenoid valve
A assembly)
– A/T clutch pressure control solenoid valve A/B
assembly
1. Check whether the scan tool or the HDS indicates
another code.
Perform the Troubleshooting Flowchart for
the indicated Code(s). Recheck for code P0740 after
troubleshooting.
Go to step 2.
NOTE: Do not continue with this troubleshooting
until the causes of any other DTCs have been
corrected.
2. Measure the line pressure (see page 14-128).
Go to step 3.
Replace the transmission.
3. Replace the Lock-up Control Solenoid Assembly set
(lock-up control solenoid valve/shift control
solenoid valve A assembly (see page 14-130) and
the A/T clutch pressure control solenoid valve A/B
assembly (see page 14-133)).
4. Clear the DTC with the scan tool or the HDS.
5. Using the scan tool, check to be sure that the
engine coolant temperature is 176°F (80°C) or
above.
6. Drive the vehicle under the same conditions as
those indicated by the freeze data for more than 1
minute, or drive the vehicle at 55 mph (88 km/h)
with TPS voltage 0.8 V for more than 1 minute.
7. Recheck for code P0740.
Inspect the O-ring on the torque converter. If
the O-ring is missing, replace the O-ring. If the O-
ring is damaged or OK, replace the transmission
and torque converter.
The system is OK at this time.
Does the scan tool or the HDS indicate another
code?
Is the line pr essur e within the ser vice limit?
Does the scan tool or the HDS indicate code
P07 40?

Problem in Shift Control Solenoid
Valve A Circuit
NOTE:
• Record all freeze data and review General
Troubleshooting Information (see page 14-3) before
you troubleshoot.
• This code is caused by an electrical circuit problem
and cannot be caused by a mechanical problem in the
transmission.
1. Turn the ignition switch OFF.
2. Disconnect the B (25P) and D (16P) connectors from
the PCM.
3. Turn the ignition switch ON (II).
4. Measure the voltage between the D7 and B20 or
B22 terminals.
Repair short to power in the wire between
the D7 terminal and the shift control solenoid valve
A.
Go to step 5.
5. Turn the ignition switch OFF.
6. Measure the resistance between the D7 and B20 or
B22 terminals.
Go to step 11.
Go to step 7.
7. Check for continuity between the B20 and B22
terminals and body ground.
Go to step 8.
Repair open in the wires between the B20 and
B22 terminals and ground (G101), or repair poor
ground (G101).

8. Disconnect the 3P connector from the lock-up
control solenoid valve/shift control solenoid valve
A assembly.
9. Check for continuity between the D7 and B20 or
B22 terminals.
Repair short to ground in the wire between
the D7 terminal and shift control solenoid
valve A.
Go to step 10.
10. Measure the resistance between the No. 1 terminal
of the lock-up control solenoid valve/shift control
solenoid valve A assembly connector and body
ground.
Check for an open in the wire between the D7
terminal and shift control solenoid valve A.
Replace the lock-up control solenoid valve-
shift control solenoid valve A assembly (see page
14-130).
11. Turn the ignition switch ON (II).
12. Measure the voltage between the D5 and B20 or
B22 terminals.
Check for loose terminal fit in the PCM
connectors. If necessary, substitute a known-good
PCM and recheck.
Check for blown No. 6 (15A) fuse in the
driver’s under-dash fuse/relay box. If the fuse is OK,
repair open in the wire between the D5 terminal
and the driver’s under-dash fuse/relay box.
